/* ** ** Swift/XRT hardness ratio for PKS 1908-201. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 54167.095777 0.039606 0.71625 0.18820 0.21615 1 0.03632 0.00616 0.02412 0.00408 0.02602 0.00522 0.01694 0.00339 54167.663190 0.336742 0.56372 0.12767 0.05397 1 0.03600 0.00508 0.01937 0.00250 0.02030 0.00359 0.01150 0.00192 54168.064569 0.009049 0.69721 0.18948 0.98127 1 0.03468 0.00604 0.02170 0.00378 0.02418 0.00505 0.01505 0.00314 54168.531167 0.408323 0.64495 0.18261 0.01979 1 0.03527 0.00629 0.02331 0.00413 0.02275 0.00500 0.01510 0.00329 54176.840676 0.070419 0.65453 0.17694 0.11456 1 0.03292 0.00565 0.02480 0.00425 0.02155 0.00450 0.01656 0.00345 55108.628790 0.038571 0.40538 0.10513 0.32390 1 0.03304 0.00463 0.02407 0.00337 0.01340 0.00292 0.00977 0.00213 55108.760360 0.040976 0.57609 0.14687 0.35996 1 0.02932 0.00455 0.01839 0.00272 0.01689 0.00342 0.01060 0.00205 55391.930651 0.036695 0.66034 0.22842 0.22834 1 0.01932 0.00424 0.01469 0.00322 0.01276 0.00341 0.00971 0.00259 56944.114450 0.033907 0.44797 0.09737 0.30402 1 0.05094 0.00623 0.03909 0.00478 0.02282 0.00410 0.01747 0.00314 56944.154037 0.005679 0.69561 0.20365 0.99488 1 0.03969 0.00750 0.02955 0.00558 0.02761 0.00617 0.02057 0.00460 56944.187881 0.028165 0.72409 0.20915 0.24760 1 0.03472 0.00657 0.02421 0.00458 0.02514 0.00549 0.01750 0.00382 56947.151555 0.006740 0.59821 0.15222 0.98491 1 0.04630 0.00725 0.03646 0.00570 0.02770 0.00556 0.02181 0.00438 56947.214494 0.005374 0.79267 0.21743 0.99082 1 0.04015 0.00736 0.03308 0.00606 0.03183 0.00650 0.02619 0.00535 56947.686297 0.009514 0.35542 0.08496 0.98700 1 0.05402 0.00666 0.04159 0.00513 0.01920 0.00393 0.01480 0.00303
